Senbazuru Izuna

Possessing the Magical Heart "Citrine"
She becomes a Jewel Princess who alternates between using a large cannon and a short handgun similar to a derringer.

With a hedonistic personality, she is an unconventional presence who hardly seems like a member of the Student Council. Often wearing a mocking smile, she frequently engages in provocative behavior. She is small and agile, displaying a so-called "bratty" demeanor.

While she does not actively support Reika's ambitions, she sometimes cooperates with her, either out of whim or affection.
